INSECT- GUARD FOR DOORS.

SPECIFICATION forming part of Letters Patent No. 524,596, dated August14, 1894.

ApplicatiOn filed July 5, 1892. Serial No. 438,917- (NomodeL) To allwhom it may concern.-

Be it known that I, HARRIET L. Lone, of West Toledo, county of Lucas,and State of Ohio, have invented certain new and useful Improvements inInsect-Guards for Doors; and Ido hereby declare that the following is afull, clear, and exact description of the invention, which will enableothers skilled in the art to which it appertains to make and use thesame, reference being bad to the accompanying drawings, and to thefigures of reference marked thereon, which form a part of thisspecification.

My invention relates to an insect guard for doors, and has for itsobject to provide means for preventing the entrance of flies, mosquitoesand other insects when the door is opened.

The invention consists in the parts and combination of parts hereinafterdescribed and pointed out in the claims.

In the drawings: Figure 1 is a front elevation of a door provided withmy improvements. Fig. 2 is a sectional detail view in side elevationshowing the door closed and the guard folded. Fig. 3 is a perspectiveview of the frame of-the guard. Fig. 4 is a detail view of a modifiedform of guard frame.

My invention is more particularly adapted to screen doors, it havingbeen observed that flies, mosquitoes, &c., gather on the screen upon theoutside thereof, and more particularly at the top, being attractedthereto by the odor escaping from the room, more especially from roomsin which cooking is done, and are in readiness to enter the room as soonas the door is opened. I have provided a guard for the top and the upperportion of the sides, by which, when the door is opened, a netting isprojected on a line nearly parallel with the top of the door, wherebythe entrance of the flies is prevented, and have so articulated theframe of the guard, that the act of opening the door expands a frame andnetting which frightens the insects away.

1 designates the door frame, 2 the door.

3 designates a rectangular frame secured within the top of the doorframe the purpose of which is to provide a support to which a nettingmay be secured. a

4 designates a rectangularframe formed with openings, 5, at each end toreceive a V screw or nail, 6, which is passed through the same, and likeopenings formed in the ends of frame 3, and into the door frame, bywhich arrangement the frame4 is allowed to swing outward, or fold withinthe door frame.

7 designates a netting secured upon frame 4, along its entire length,and also upon frame 4 its entire length, and of a width to allow theframe 4 to fall from a vertical position to an angle of approximatelyforty five degrees from the pivotal point of the same when the door .isopened.

8 designates a spring secured to the inner end of the guard,or the endnearest the door,

the opposite end being secured to the door at 9, with a coiled portionextending beyond and secured to the door at 9' whereby the spring exertsan outward pull upon the guard at all times. I

Upon each outer corner of the frame 4 is formed buffers 10, whichcontact with the door, and prevent wear of the netting or frame.

In operation, the door being closed, and any number of insects gatheredupon the up per portion of the same in readiness to enter the room whenthe door is opened, the act of opening the door extends the guard andnot only prevents entrance, but frightens the insects from the door, andwhen the door is closed the guard is compactly folded within the doorjamb:

It will be apparent that I may dispense with the spring 8, and employ acord or other flexible connection to expand the frame 4, and allow thedoor to close the frame if desired, or the frame may be arranged to dropby its own weight and be folded back by shutting the door.

In Fig. 4 the frame 3 extends along but one side of the door frame, andis formed with a loop 11 into which is yieldingly secured a bar 12 whichextends at an angle horizontally from the frame 3, and is projectedoutwardly at the outer end by means of a coiled spring 13 secured toframe 3 and the bar, the throw of the spring beinglimited by a cord 14.This arrangement is convenient when the door is to be opened but partway, as in this case the bar 12 is at an angle corresponding to theradial movement of the door upon its hinges, this latter construction isinterchangeable, or adapted to doors swinging either way, as the frame 3is first secured to the door frame, and

afterward the bar is secured to the loop upon the side to project thesame to the. inclination. of the door when opened.

What I claim is-- 1. In an insect guard, the combination with a fabricsecured. Within the door frame, of a bar pivotally arranged within thedoorframe,

' and to which the fabric is connected, said bar being so connected thatwhen the door is.

opened the bar will move toward the same to expand the cloth and befolded back by the closing of the door.

2. A guard for doors comprising a rectangular frame secured-withinthedoor jamb, a frame pivot-ally connected with the same, a

- foraminous covering extending from one frame to the other, and aconnection from the door to the frame to extend or fold the piv- I otedframe' as the door is opened or closed respectively. r

3. In an insect guard, the combination with essentially rectangularframe, secured to the door jamb, a fabric secured to said frame, a

"barpivotallyconnected with said frame and also connected with thefabric and a spring for moving said bar outward to expand thefabric'when the door is opened.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence'of two witnesses.

I HARRIET L. LONG.
